I pair the Aesthetix Calypso linestage rolled with (2) NOS Mullard CV4004 and (2) NOS Philips Holland SQ E188CC/7308 with a BAT VK-55SE (stock,so far) and have listened, enraptured, to the HE-6 for hours. Spinning the discs with the oh so musical presentation of the Marantz SA-7S1 SACD player completes the chain. This is my preferred rig and I listen to it much more often than the LCD-3 through the Bakoon AMP-11R and the ATW3000ANV plugged into the EAR HP4, both of which are able to make the magic on their own accord.
I think I have finally reached the stage where the HE-6 is fully broken in and they are addicting. My favorite can!
